Description
Technical field rock mechanics experiment technology and apparatus field
Background technique world today resources exploration is drive on boldly to earth energy and disaster, crustal stress on-the-spot test
Statistics indicate that the crustal stress level of 3500~5000m depth can reach 95~135M Pa, the exploitation of this kind of resource need to use ultra-deep
Drilling well and must to reservoir carry out geologic body fracturing reform, this is just needed in laboratory simulation large scale (0.4 meter of >) cube
Drilling and fracturing process of the rock sample under Deep ground stress effect, testing machine is needed in each acting surface in this case
Upper output and the substantially comparable payload values of Deep ground stress level, need if the stress on each acting surface reaches 100 MPa
To export 1600 tons of pressure on each face, current testing machine hydraulic cylinder due to sealing technique limitation and this can not be exported
Kind of horizontal stress, this, which just directly results in oil cylinder piston, output phase to work as the load of stress level on respective action face, this
It is a technical problem.
The summary of the invention present invention provides one kind and gives large scale (0.4 meter of >) cube rock-like in rock mechanics experiment
The seperated multilayer linkage pressurizing cylinder of high stress level is exported on product loading end.It is characterized in that using the concatenated mode of multilayer oil cylinder
It is pressurized to realize, solves the problems, such as the big load of output；The pressurizing piston of multilayer oil cylinder is connected by screw bolts, and realizes multilayer oil cylinder
The flexible consistency of piston；The cylinder body and piston of every layer of oil cylinder in multilayer oil cylinder can be processed individually, and processing can be reduced
Difficulty and guarantee processing precision；Seperated multilayer linkage pressurizing cylinder is assembled by monomer oil cylinder, and oil inlet and oil return are equal
It is realized by the one-way cock being located on bottom cylinder body；Each layer oil cylinder in top is connect with bottom oil cylinder by upper and lower cavity access,
Realize fuel feeding and synchronism output load simultaneously.Seperated multilayer linkage pressurizing cylinder can export the load much larger than monomer oil cylinder
Value, to lay the foundation in laboratory simulation deep layer crustal stress.
Basic principle is with technology: seperated multilayer linkage pressurizing cylinder is to utilize the original to interconnect between seperated multilayer oil cylinder
Monomer oil cylinder on common meaning is layered superposition, by each layer in the case where cylinder interior maximum oil pressure value size determines by reason
The pressurizing piston of oil cylinder realizes linkage by screw rod connection, and the forced area of such multilayer piston increases compared with conventional monomeric oil cylinder
Greatly, piston forced area increase can make the increase of whole oil cylinder output pressure, to obtain higher output pressure, realize
The purpose of pressurization.
It is this fission multilayer link pressurizing cylinder, by the unidirectional oil inlet 1 of process, the unidirectional oil outlet 2 of process, bottom cylinder body 3,
Bottom piston 4, process upper and lower cavity access 5, backhaul upper and lower cavity access 6, middle layer piston 7, middle layer cylinder body 8, the unidirectional oil inlet of backhaul
9, the unidirectional oil outlet 10 of backhaul, upper layer cylinder body 11, Piston attachment bolts 12, upper layer piston 13, lower oil cavitie 14 in process, in backhaul
Lower oil cavitie 15 forms.Seperated multilayer linkage pressurizing cylinder due to inputting in process upper and lower cavity 14 simultaneously in process output pressure
High pressure liquid pressure oil simultaneously acts on bottom piston 4, middle layer piston 7 and upper layer piston 13, in this way can compared with conventional monomeric oil cylinder
To increase piston compression area effectively to improve oil cylinder output pressure.
Detailed description of the invention
Attached drawing 1 is seperated multilayer linkage pressurizing cylinder sectional front view, and attached drawing 2 is that seperated multilayer linkage pressurizing cylinder is overlooked
Sectional view.
1: the unidirectional oil inlet of process；2: the unidirectional oil outlet of process；3: bottom cylinder body；4: bottom piston；5: process upper and lower cavity
Access；6 backhaul upper and lower cavity accesses；7: middle layer piston；8: middle layer cylinder body；9: the unidirectional oil inlet of backhaul；10: backhaul is unidirectionally fuel-displaced
Mouthful；11: upper layer cylinder body；12: Piston attachment bolts；13: upper layer piston；14: process lower layer oil pocket；15: process middle layer oil pocket；
16: process upper layer oil pocket；17: backhaul upper layer oil pocket；18: backhaul lower layer oil pocket.
When specific embodiment 1. is further applied load, high pressure liquid pressure oil passes through the unidirectional oil inlet 1 of process first and enters under process
Layer oil pocket 14 goes successively to process middle layer oil pocket 15 by process upper and lower cavity access 5 full of rear high pressure liquid pressure oil and is full of intracavitary
Space, subsequent high pressure liquid pressure oil go successively to process upper layer oil pocket 16 until high pressure liquid pressure oil is full of cavity space.
2. with high pressure liquid pressure oil continue by the unidirectional oil inlet 1 of process enter oil cylinder, bottom piston 4, middle layer piston 7 and
Upper layer piston 13 realizes that synchronized process is under the effect of high pressure liquid pressure oil come output pressure by the connection of Piston attachment bolts 12, most
End pressure by upper layer piston 13 export and directly act on rock sample, after reaching scheduled pressure value, stop process unidirectionally into
Hydraulic fluid port 1.
3. high pressure liquid pressure oil is entered backhaul upper layer oil pocket from the unidirectional oil inlet 9 of backhaul after the completion of test pressure effect
17 and be full of cavity space, later high pressure liquid pressure oil by backhaul upper and lower cavity access enter backhaul lower layer oil pocket 18 and be full of it is intracavitary
Space, as high pressure liquid pressure oil continues to enter oil cylinder by the unidirectional oil inlet of backhaul, bottom piston 4, middle layer piston 7 are in high-pressure and hydraulic
Oil effect is lower to start backhaul, and under the drive of Piston attachment bolts 12, upper layer piston 13 is also synchronous to start backhaul, and final bottom is living
To initial position, entire pressure-loaded process terminates for plug 4, middle layer piston 7 and the equal backhaul of upper layer piston 13.
